Types ¶

type I2C ¶

type I2C struct {
	// contains filtered or unexported fields
}

func OpenI2C ¶

func OpenI2C(device int, addr uint8) (*I2C, error)

func (*I2C) Close ¶

func (c *I2C) Close() error

func (*I2C) Read ¶

func (c *I2C) Read(p []byte) (int, error)

func (*I2C) Reset ¶

func (i *I2C) Reset() error

Reset does nothing (for now?).

func (*I2C) String ¶

func (c *I2C) String() string

func (*I2C) Write ¶

func (c *I2C) Write(p []byte) (int, error)

type SPI ¶

type SPI struct {
	// contains filtered or unexported fields
}

SPI implements the spidev interface.

func OpenSPI ¶

func OpenSPI(bus, device int) (*SPI, error)

OpenSPI opens the numbered spi bus with the numbered device. The device often corresponds to the CS pin for that bus.

func (*SPI) BitsPerWord ¶

func (c *SPI) BitsPerWord() uint8

func (*SPI) Close ¶

func (c *SPI) Close() error

func (*SPI) MaxSpeed ¶

func (c *SPI) MaxSpeed() int

func (*SPI) Mode ¶

func (c *SPI) Mode() SPIMode

func (*SPI) Read ¶

func (c *SPI) Read(b []byte) (n int, err error)

func (*SPI) SetBitsPerWord ¶

func (c *SPI) SetBitsPerWord(bits uint8) error

func (*SPI) SetMaxSpeed ¶

func (c *SPI) SetMaxSpeed(v int) error

func (*SPI) SetMode ¶

func (c *SPI) SetMode(mode SPIMode) error

func (*SPI) String ¶

func (c *SPI) String() string

func (*SPI) Write ¶

func (c *SPI) Write(b []byte) (n int, err error)

type SPIMode ¶

type SPIMode uint8

const (
	SPIMode0 SPIMode = (0 | 0)             //nolint:staticcheck
	SPIMode1 SPIMode = (0 | spiCPHA)       //nolint:staticcheck
	SPIMode2 SPIMode = (spiCPOL | 0)       //nolint:staticcheck
	SPIMode3 SPIMode = (spiCPOL | spiCPHA) //nolint:staticcheck
)
